. 17 Claims. (Cl. 1554$) The present invention relates to a roller type device for applying a liquid to a surface to be coated and the invention more specifically pertains to a roller applicator for applying paint to a wall or the like wherein the liquid is supplied through the interior of the roller to the outer shell by a pump assembly or pump means arranged within the roller which serves to move liquid from a supply or reservoir to the perimeter of the roller.

It is known to force liquid such as paint into the interior of a roller type applicator by means of compressed air developed in a pressure supply tank for the paint or the like. As distinguished therefrom the present invention is directed to pump means incorporated within the roller itself which is set in operation by rotation of the roller to deliver liquid from a supply or a container into the roller and into the presence of the outer shell for transfer onto a surface to be coated. 7

An object of the invention is to provide pump means in combination with a roller type liquid applicator which functions to pump liquid from a supply or reservoir into the roller and to a position for being transferred from the outer shell of the applicator onto surface to be coated.

Another object of the invention is to provide a roller type device for aplying a liquid to a surface with a pump mechanism within the roller driven by rotation of the roller applicator with the pump elements so arranged as to avoid enlargingthe size of the roller and without materially increasing the weight of the applicator and with elements of the pump means being readily dismantled to facilitate cleaning of the parts which are subiected to the presence of the liquid or paint.

A further object of the invention is to provide means for controlling the quantity or rate at which the liquid is moved by the pump means into the roller.

3,187,368 Patented June 8, 1965 'ice The assembly is desirably constructed to be portable and a handle 10 adapted to be gripped by the hand of an individual has an opening therethrough for receiving and supporting a straight portion .11 of a tube 12 which is substantially rigid and may be formed of metal. The handle is aligned with a mid-portion of a roller assembly 14 and it is for this purpose that the tube '12 has angular portions and an end portion 16 remote of the handle which is straight and serves as a hollow stationary shaft for the roller as hereinafter described. The paint or other liquid may be stored in a container 17 which is connected by a flexible conduit or hose I18 to the tube portion 11 in any suitable manner and preferably at the free end of the handle 14). The container 17 may be formed of flexible material and provided with a sling or strap 19 for supporting the container with a supply of liquid therein from the shoulder or the neck of an operator.

The container 17 may be of such construction that the liquid or paint is not exposed to the atmosphere whereby the liquid is completely encased from the supply to the interior of the roller assembly 14.

A mechanism or means for delivering liquid from the container 17 into the interior of the roller assembly 14 is shown-in FIGS. 2 and 3.. The roller structure which also forms parts of the pump mechanism includesan elongated tubular member @1 which is substantially cylindrical shaped. The member 21 is provided with an annular recess on the periphery thereof throughout the length thereof except for end lips 22. The recess provides an annular space 23 between the perimeter of the member 21 and a conventional textile type outer shell 24 having interstices or openings 25 through the web portion so that the liquid may pass to the elements 26 which serve Other objects and featuresof the invention will be detailed description taken in conjunction with the ac-- companying drawing wherein several exemplary embodiments of the invention are disclosed.

In the drawing: g PKG. 1 is a side elevational view of a roller liquid applicator embodying the invention and illustrating a con-v tainer for a supply of liquid with a flexible conduit extending therefrom to the applicator.

FIG. 2 is an enlarged axial sectional View of the roller and pump assembly of FIG. 1.

FIG. 3 is a transverse sectional view taken on the line 33 of FIG. 2.

FIG. 4 is an axial sectional view of a roller applicator with the pump elements of the combination constituting a modification.

FIG. 5 is an enlarged sectional view of the valve structure associated with the supply line for controlling the volume of liquid delivered into the roller.

An applicator embodying the invention has particular utility for applying paint to walls or the like and the roller and pump mechanism avoids the necessity of dipping the applicator into a supply of paint. The paint applying roller with the pump means incorporated therein functions to draw paint from a container holding a supply of liquid and deliver it into the roller and to the outer shell of the roller by the manual maneuvering of the applicator and by causing the periphery of the device to roll on the surface to be painted.

the member 21.

to transfer the liquid onto the surface to be treated.

The' member 21 is adapted to rotate about the axis of the straight portion .16 of the tube 12.- A substantially disc-shaped member 27 is carried by the shaft portion 16 of the tube and the periphery of the disc-shaped member 27 serves as a bearing support for one end portion of A transverse web or partition 23 which may be formed integral with the member 21 has an axial opening therethrough for accommodating the free end of the hollow shaft 16 and this part of the shaft serves to support another portion of the member 21 for rotation. Gasket means 29 may be provided to prevent leakage of the liquid through the journal opening in the partition 28.

The member 27 is secured to the shaft portion 16 of the tube in fixed relationship or formed integral therewith so that it remains stationary and fixed with respect to other elements of the assembly. Oneor more pins 31 extend in parallel relationship from the member 27 and substantially parallel to the shaft portion 16 as shown in FIG. 2. A cylinder isformed within the intermediate portion of the member 21 and the bore of the cylinder is indicated at 34?. The cylinder is closed at one end by the partition 28. A piston 32 is mounted for reciprocating movements within the cylindrical borefiii. The piston 32 is slidable on the straight shaft portion 16 of the tube 12 and carries gasket means at its perimeter and around the straight shaft portion 16 of the tube to prevent leakage of liquid from the chamber 34. The member 21 beyond and spaced from the cylinder bore 30 is provided with coarse threads 37 which have a high pitch. A disc-shaped element 38 is connected to the piston 32 by a tubular element 3 9 to provide a plunger member. The exterior of the element 38 is provided with threads 41 engageable with the threads 37.

During rotation of the roller member 21 the threads 37 turn therewith but the element 38 is retained from rotation by means of the pins 31 which extend through openings in the disc element 38. Accordingly the plunger and the piston 32 moves axially with respect to the shaft portion 16 of the tube 12. In one embodiment the threads 41 escape from the end of the threads 37 after approx1- mately four revolutions of the roller member 21. The assembly includes resilient means urging the plunger member including the disc element 33 to a position for reengaging the threads 37 when rotation of the roller member 21 is reversed. Such resilient means may take the form of a helical spring 42 arranged within the chamber 34 and surrounding the hollow shaft 16 with one end abutting the partition 23 and the other end abutting the piston 32. Another spring 43 or resilient means surrounds the hollow shaft 16 with one end in abutting relationship with the disc element 38 within a cavity therein while the other end of the spring 42 abuts the member 27 within a confronting cavity.

A plurality of radially disposed holes or discharge ports 46 are provided through the roller member 21 with the inner ends thereof in communication with the cylinder chamber 34. In operation liquid is forced outwardly through these holes into the annular space 23. Valve means for the discharge ports 46 may take the form of an elastic band 47 which surrounds the member 21 and overlies the exit ends of the holes 46. A plurality of inlet ports or opening 48 are provided through the wall of the hollow shaft 16 within the chamber 34. Liquid is drawn into the cylinder chamber 34 through the openings 48 during the suction stroke of the pump and valve means which may take the form of an elastic or rubber band '49 overlies the exit ends of the ports 48 and serves to prevent the return of the liquid from the chamber 34 into the tube 12 during the expulsion stroke of the piston 32. The combination is assembled by introducing the piston 32 and the plunger member into the cylinder bore 30 and thereafter the member 21 with the elastic band and the outer shell theron is moved to the right in FIG. 2 over the hollow shaft portion 16 until the shoulder 51 on the member 21 engages the disc member 27. The opening of the partition 28 then accommodates the free end of the hollow shaft portion 16 of the tube. A retaining member 52 is then arranged within the end of the member 21. The retaining member is provided with wings 53 for rotating a threaded inner end threads carried by the interior of the hollow shaft 16. An annular shoulder 56 on the retaining member serves as an abutment to maintain the shoulder 51 in operative relationship with the inner face of the disc member 27 and to retain the partition 28 in operative association with the free end of the hollow shaft 16.

In operation and during rotation of the roller member 1 21 in one direction the plunger is moved to the right in FIG. 2 to develop suction in the tube 12 and to draw liquid from the container 17 through the conduit 18 and the tube 12 into the chamber 34 through the openings 43. During the suction stroke the elastic band 49 is distended outwardly. Continued rotation of the roller member 21 and the outer shell carried thereon in the same direction causes the threads 41 to escape from the threads 37 and this completes the suction stroke. During such movement the spring 43 is compressed and the threads 41 are held in position to reengage the threads 37 upon rotation of the member 21 in an opposite direction. In carrying out a paint applying or coating operation the roller is manipulated manually and the member 21 takes up rotation in a direction opposite to that just described. The element 38 is then shifted to the left compressing the spring 42 and the piston 32 moves to the left in FIG. 2 forcing the liquid trapped in the chamber 34 outwardly through the discharge holes 46 and into the annular re- ,cess or space 23. The elastic band 47 yields to permit the escape of the liquid from the chamber 34 and serves as a valve preventing the return of the liquid inwardly through the discharge holes 46. The spring 42 is compressed and the energy stored therein during the expulsion stroke of theplunger nernber,maintains the disc element 54 into threaded engagement with of the member 21a the tubular element 39a is moved 4 38 in position to reengage the threads 37 upon rotation of the member 21 in the first described direction,

A modification is shown in FIG. 4 wherein a diaphragm 56 replaces the piston 32 and the gaskets associated therewith. In this embodiment the disc member 27a is provided with an annular extension 57 which forms a larger bearing surface for the member 2111. The annular extension 57 carries the threads 37 which remain stationary because the member 27a is carried by the hollow shaft 16 in fixed relationship. The periphery of the diaphragm 56 is clamped between a shoulder 58 formed on the member 21a and the end 59 of a ring member 61. The ring member 61 is in abutting relationship with the end of the annular extension 57 and upon tightening of a retaining member 52a the perimeter of the diaphragm 56 is sealed with respect to the member 21a and the ring member 61. A key 62 carried by the member 61 extends into an axially disposed groove 63 in the tubular element 39a. The key 62 provides a driving connection between the member 21a and the tubular element 3%. Thus the disc shaped element 35561 is rotated to shift the tubular element 32a axially on the holloW shaft. The inner circumference of the diaphragm 56 is clamped to and maintained in sealed relationship with .the end of the tubular element 3% and the perimeter of the hollow shaft 16. The diaphragm 56 has resilient characteristics so that when the inner portion is deformed axially of the chamber 34 it serves to urge the tubular element 3% and the disc element 38a in an opposite direction so that the threads 41 are in a position to reengage the threads 37.

In this embodiment the device is assembled by arranging the disc element 38a in a neutral position with respect to the threads 37. The ring member'61 is then applied with its end in abutting relationship with the free end of the annular extension 57 after the key 62 is in position within the groove 63. The member 21a is applied to the right in FIG. 4 until the shoulder 58 engages the perimeter of the diaphragm 56. The opening in the partition 28 then accommodates the free end of the hollow shaft 16. The retaining member 5211 is then applied with the threaded end engaging the interior threads of the hollow shaft 16. A helical spring 66 serves to bias the member 21a to the right in FIG. 4 holding the elements in assembled relationship.

The pump means incorporated in the roller applicator 'shown in FIG. 4 functions in a manner similar to that described in connection with the first embodiment. The

ring member 61 and the diaphragm 56 rotates with the member 21a. The key 62 extending into the groove 63 7 causes the tubular element 39a to rotate about the axis of the hollow shaft 16. The disc element 38a rotates in one direction causing the tubular element 39a to shift axially distorting the diaphragm 56 and creating a suction stroke drawing liquid into the chamber 34 through the inlet openings 48. The resilient character of the diaphragm 56 serves to maintain the threads 41 in position to reengage the threads 37. Thus upon reverse rotation axially to provide an expulsion stroke of the pump means. Liquid is then forced from the chamber 34 through the discharge holes 46 into the annular space 23.

The assembly includes means in association with the supply line to control the quantity of liquid delivered by the pump means. Such means is shown generally at 68 in FIGS. 1 and 5 and provides for admitting controlled quantities of air into the tube 12 which is provided with an aperture 71. A valve housing 72 encases the tube 12 in the vicinity of the aperture 71. It is provided with interior threads 73 receiving exterior threads 74 on a stem 76.

An axial passage 77 is provided in the stem in communication with a transverse passage 78. A cage 79 on the inner end of the stem 76 contains a ball 81 of smaller diameter than the cage 79. When the stem 76 is adjusted to an outer position by turning the knob air is admitted through the passage 78 and the passage 77 around the ball 81 and through the aperture 71. The valve mechanism serves to prevent the outward flow of liquid from the tube 12 because the ball 81 then closes the cage in the area 82. The control valve of FIG. 5 may be employed with either modification and may be adjusted to admit limited quantities of air to the tube 12 and thereby control the quantity of liquid delivered by the pump means.

While the invention has been described with particular reference to a roller type applicator with pump means therein for delivering paint to the outer shell of such a device it will be appreciated that it may be used for other liquid applying purposes. Changes may be made in the structure of the roller as well as the pump elements. Such modifications and others may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
